We bought this for our adult daughter as a gift. She has been playing for many years and missed playing when she moved into a smaller apartment that couldn't accommodate a piano. She's thrilled with it and enjoys playing it very much and she can play anytime she wants since she can plug in the earphones so only she can hear. I recommend buying the power supply so you don't always have to use all those batteries and also the foot pedal so it helps to make it sound even more like an actual piano.

I brought this for my wife as her Xmas present as she was missing her many years old keyboard that stop working some time ago. She is delighted, finds it easy to use, loves the many different voices. The only "snag" that I can see is that the keyboard is quite large and bulky and that you will need to buy the separate power adapter or you will burn through a lot of AA batteries. Overall an excellent product.

We are having a great time with this keyboard - our whole family is getting involved, and we love it. It is easy to uae and has so many options that we have barely begun to get the full enjoyment of it -admitally, we have only had it for a couple of weeks. Easy to use and sounds great.I would recomment that the box that it is shipped in be placed inside another box to hide the lettering - for security reasons so that its contents would not be disclosed. Also the box came with a puncture hole in it. The contents (keyboard) was not damaged, but the box is obviously not strong enough to withstand abuse from the shipper.
